PCOS and nutritional approaches: Differences between lean and obese phenotype

Area of Science:

• Endocrinology and Metabolism
• Reproductive Health
• Nutritional Science

Background:

• Polycystic Ovary Syndrome (PCOS) is a prevalent endocrine/metabolic disorder characterized by androgen excess, ovulatory dysfunction, and metabolic alterations like insulin resistance.
• PCOS affects both obese and lean women, who exhibit distinct body composition and metabolic profiles despite shared features.
• Tailored therapeutic strategies are crucial for effective PCOS management, considering individual patient phenotypes.

Purpose of the Study:

• To review current literature on body composition and nutritional strategies for lean and obese PCOS patients.
• To analyze the specific metabolic and body composition characteristics differentiating lean and obese PCOS phenotypes.
• To evaluate diverse nutritional interventions for managing PCOS symptoms, including insulin resistance and infertility.

Main Methods:

• Systematic review of updated PubMed publications.
• Focus on studies investigating body composition and nutritional interventions in PCOS.
• Analysis of metabolic characterization and dietary patterns.

Main Results:

• Dietary patterns are fundamental in managing PCOS, impacting insulin resistance, infertility, and cardiometabolic health.
• Lean and obese PCOS patients present unique metabolic profiles and body composition, necessitating individualized approaches.
• Various dietary strategies have shown potential in improving PCOS-related dysfunctions.

Conclusions:

• Personalized nutritional strategies based on body composition and phenotype (lean vs. obese) are essential for optimizing PCOS treatment outcomes.
• Further research into tailored dietary interventions can enhance the management of insulin resistance, infertility, and cardiometabolic issues in PCOS.
• Understanding the specific needs of lean and obese PCOS patients is key to developing effective, individualized therapeutic plans.
